Fig. 9 is a sectional view taken substantially through V9--9 of Fig. 8,showing the window control device in plan.

The window control device is illustrated in Figs. 1

` through 3 and 5 through 9 as adapted to a typical metal windowstructure.

mA typical or conventional window structure includes Va metal windowframe 1 formedofextruded metal so vas to denne an interior, inwardlydirected lip 2connected by a web 3 toan exterior, outwardly directedlipr4.

"ice

2 The window frame is 'intended to be mounted within a window opening.

Fitted within the window frame 1 is a window sash S which is likewiseprovided with `an interior inwardly directed lip 6 connected by a web 7to an exterior, outwardly directed lip 8. The lips of the window sash 5bear against the lips of the window frame l when the window sash is inits closed position, such as shown in Figs. 1, 2, and 3. The window sashreceives'a windowl pane 9 which is heldin place against the lip 6 by aretainer member 10.

The window sashv 5 is pivotably connected to the window frame by varioushinges or mounting devices, not shown. One such type of mounting deviceis shown in Patent No. 2,784,459, lissued March l2, 1957. The windowsash may be mounted so as to pivot about a horizontal axis or about avertical axis, in which case the window control device is mounted at thetop or bottom of the window, or at the side thereof, as the case may be.It is customary to mount on the interior side of the windowV frame 1 awindow screen sash 11 containing a window screen 12. The`window screensash is in the form of a thin metal frame which overlaps the margin ofthe lip 2.

The window control device includes a sash bracket 13 which is secured tothe window sash 5 at one side thereof between the web 7 and thecorresponding outwardly directed lip 8 so that whenthe window sash is inits closed position the `sash bracket 13 is disposed beytween the web 7andthe Web 3. y

The sash bracket 13 includes a pair of right angularly disposed flanges14 and 15, confronting, respectively, the web 7 and lip 8. One or bothof these flanges may be secured by means of rivets or screws. The sashbracket isv divided lengthwise by partitions 16 having slots 17 thereinwhich slidably receive a cross bar 18.

The cross bar 18 is secured to or journals a link member 19, whichextends outwardly from the sash bracketl 13. The cross bar permitspivotal movement of the link member about an axis parallel to the sideof the Window sash 5 on which the sash bracket is mounted as Well aslimited sliding movement.

The ends of the partitions 16 remote from the flange 15 are joined topartial walls 20 which in turn are joined to partial partitions 21directed toward the anges 15 parallel to the partitions 16. Thepartitions 16, walls 20, and partial partitions 21 form housings orpockets for compression springs 22 anchored to the extended ends of thecross bar 18 so as to urge the cross bar and link member 19 toward theflange 15, that is, tow-ard its retracted position. j

The extended end of the link member 19 is divided to 'form a yoke23fwhich is provided with a journal rivet 24 defining an axis at rightangles to the cross bar 18. The yoke 23 receives a push bar 25 which isjournaled by the rivet 24. The push bar 25 is in the form of'an arcuateystrap and is slidably received in a push sleeve 26 which is alsoarcuately curved.

The push bar 25 is provided near its end remote from the yoke 23 with apush button 27 backed by a leaf spring 28 and arranged to enter aperforation 29 provided inthe push sleeve 26. In the construction shown,a perforation 29 is provided near each end of the push sleeve 26 so thatthe push bar 25 may be latched in a telescoped or retracted positionrelative to the push sleeve, as shown in Figs. l, 2, and 7, or in anextended position relative to the push sleeve 26, as Ashown in Figs. 8and 9. The extended 'end of the push sleeve 26 is. provided with ahandle 30 which may terminate in a linger loop.

One side of the inwardly directed lip 2 of the window frame 1 isprovided with an, aperture lin alignment with the sash bracket 13 overwhich is mounted a guide bracket 31.Y The guide bracket is provided withlateral ears which receive screws for attachment to the window frame.The'g'uide bracket may have a projection 32 whichfits within and linesthe aperture. s f' The guide bracket 31 is provided with arectangularslot 33 which slidably Vreceives the push sleeve 26 and push bar 25. Theinterior end'of the slot 33, that is, the end remote from the projection32, is preferably ared as indicated by 34. f

The link member 19 has suicient length that when the window sash 5occupies its closed position, such as shown in Figs.' l, 2, and 3,thepush bar 25 and push sleeve 26 may be pivoted about the axis of thejournal rivet 24, so that the push barmay be forced to a positionparallel with the window frame 1 by fulcruming the push bar 25 over amargin 35 of the guide bracket 31. This action draws the window sashinwardly against the window frame, against the compression of thesprings 22.

A latching bracket 36 is provided at one side of the guide bracket 31and is provided with a hook end 37 whichV retains the push sleeve 26 inits laterally extending or locking position. Y

Operation ofthe window control device is at follows:

When it is desired to open the window sash 5 from the position shown inFigs. 1, 2, and 3, the push sleeve 26 is first depressed slightly todisengage the hook end 37 of the latching bracket 36, and then rotatedabout the pivotal axis of the push bar 25 in alignment with the linkmember 19. The push bar and push sleeve are then pushed outwardlythrough the guide bracket 31 so as to swing the window sash 5 toward theposition shown in Fig. 7.

The extremity of the push sleeve 26 forms a shoulder 38 which engagesthe margin of the slot 33 so as to hold `the window sash extended. If itis desired to extend the window sash further, the button 27 is initiallydepressed and the push sleeve pulled outwardly relative to the push bar25 until the button engages the other perforation, whereupon the pushbar and push sleeve are forced through the slot 33, pivoting the windowsash to the position vsuch as shown in Figs. 8 and 9. In this case,also, the shoulder 38 engages the slot 33 to hold the window sash in itsextended position.

To retract the window sash 5V it is merely necessary to disengage theshoulder 38 from the margin of the slot 33 and pull the push sleeve 26inwardly. When the window sash reaches its closed position the pushsleeve is then displaced angularly relative to the link member 19. Whenthe push sleeve 26 is in its extended position, the button 27 isdepressed to permit telescoping of the push sleeve 26 over the push bar25 are pivoted to the position shown inFigs. l, 2, and 3, causing thepush bar 25 to fulcrum over the margin 35 of the guide bracket 31 anddraw link member 19 in opposition to the springs 22 whereby thecompressive forceA of the springs urges the window sashl 5 into a snugsealing engagement with the window frame 1. Y

- Reference is now directed to Fig. 4. This construction is essentiallythe same 'as the previously described structure. However, the guidebracket 31a may be modified so as to be secured to the top of a woodensill 39, and the wooden window sash designated 40 may be provided with arecess or pocket to receive the sash bracket 13. The operation of thewindow control device as installed on a wooden window frame and windowsash s identical to the operation of the control device as mounted on ametal ,window frame and window sash.

.ing a window frame yand a pivotable window sash, com- It is sometimesdesirable, in order to facilitate cleaning of the window, that controldevice be disconnected and permit movement unrestrained by the controldevice. This can be readily done by depressing the push button andcompletely push bar. f Y l p It will be observed that the push bar 25may be pivoted withdrawing the push sleeve from the in eitherdirectionrelative to the guide bracket 31 for either left or righmounting of the window control device.

While particular` embodiments of this invention have been shown anddescribed, it is not intended to limit the same to ythe exact details ofthe; constructions set forth, and it embraces such changes,modifications, and equivalents of the parts and their formation andarrangement as come withinY the purview of the appended' claims.
